不同移栽期对烤烟产质量的影响研究

Effects of Transplanting Time on Yield and Quality of Flue-Cured Tobacco

摘要: 试验研究了衡阳市祁东县烟区不同移栽期对烟叶生长发育及产质量的影响。结果表明，以3月6日为最佳移栽期，该处理的烟株生长发育较好，产量、产值均较高，烤后烟叶橘黄色比例高，成熟度好，结构疏松，油分充足。因此建议衡阳市祁东县烟区每年在3月6日前后盖膜移栽，采取膜下小苗深栽技术，提高烟苗成活率，缩短烟苗还苗期，延长烟叶大田期，提高烟叶成熟度，充分保障烟草工业企业优质原料需求。

Abstract: The effects of transplanting time on the growth yield and quality of flue-cured tobacco in Qidong County Hengyang City were studied through a randomized block field experiment. The results showed that transplanting tobacco seedlings on March 6th was the most appropriate among different transplanting time treatments. The growth and development of tobacco plants which were transplanted on March 6th were better, the yield, maturity and output value were higher, the structure is looser and the oil content is abundant. Therefore, the best transplanting time of tobacco in Qidong County Hengyang City should be March 6th. By adopting the technology of deep planting of seedlings under the film, the survival rate of tobacco seedlings can be improved, the seedling returning period can be shortened, the field period of tobacco can be prolonged, the maturity of tobacco can be improved, and the high-quality raw material demand of tobacco industry enterprises can be fully guaranteed.
